About the point 2, I did some modifications to the surface_dynamics
package that allows it to be compiled on archlinux (there was some
trouble of include paths with Cython). In order to try the changes
just run
$ pip2 install git+https://gitlab.com/videlec/surface_dynamics --user
In the future (i.e. next release) you will be able to do directly
$ pip2 install surface_dynamics --user
I might find the time to make it a proper archlinux package...
Please report back if anything went wrong.

Hi all!
Installing sage (8.2) from maintained repo on Arch linux provided a low
functioning installation which symptoms are given here in the end. I then
tried to build sage from source, failing with a "generate-posix-vars
failed" and segfault. This issue resembles
https://bugs.python.org/issue33374 and https://bugs.python.org/issue21166
yet I could not deduce a solution to my case.
System: ver 4.17.4 kernel, with gcc 8.1.1. Has python 2.7.15 installed
CPU: Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz, 4 cores
As for the packaged installation problem, two examples are:
1. sage --testall fails to start, returning:
Setting permissions of DOT_SAGE directory so only you can read and write it.
no stored timings available
Running doctests with ID 2018-07-08-11-31-28-50157d1f.

2. installation of packages fail due to some environment confusion, for
example:
[amit@amit-desk sage-8.2]$ sage -pip install surface_dynamics

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in

I tried to search for leads from these two, but couldn't understand the
underlying problem.
Many thanks in advance,
Amit.
